Great news, I just watched the Video and am super excited to see if it works for the Vibrant.
[Vibrant Android Development] Emama:
same here, cant wait for an official update!!!
[Vibrant Android Development] techspy:
I have seen references to checking the time server in the gps config file, and mine seems to be correct, however my GPS (in all test programs) shows the wrong local time. It is 5 hours fast. I can't help but think that has somethign to do with my crappy GPS lock times and accuracy. I have gotten 3 locks at most and usually only get 1 and sometimes 2. The stupid thing is that it locks on signals that are obviously not the strongest signals. I can see 40+ DB on some but it locks on one that flucuates between 0-30.

I know this is all old news but does anyone have any idea how to correct the time that the GPS thinks is local? FYI, I have deleted GPS data, confirmed my handset time is correct and even tried setting it manually. Same issue.

Thanks
[Vibrant Android Development] bradycl_84043:
I was wondering about this in another thread... I do think that this has to somehow be related. GPS Test reports that the local time being used by the GPS is 7 hours fast. It *does* know what time zone I am in, as it correctly is reporting UTC as local time+6 (I am in Mountain Daylight time), but it is reporting that as the *wrong* local time+6, so again, 7 hours fast. Since all GPS satellites do is sit there and squawk the time, you'd think that having the right local and UTC would be pretty important.

Just a theory, mind you, but I think perhaps it's looking at the satellites it sees and the time, realizing that it can make no sense of seeing that set of satellites in that position at that time, comparing to the network fix, and eventually settling on locking just the sattelites that it *would* be able to see in the sky at this location at that time.
[Vibrant Android Development] Qverse:
Well GPS still Bad

I still pissed about this GPS issue . I have try every thing and every way... and still no fast lock .. I fact most of the time , GPS never locks on.. i hoping someone would come up with a answer ...Is it a software or hardware problem...?? As much as this screen and CPU/GPU is Great ! This tracking issue is driving me crazy... I held out so long on the G1. So now I miss that quick tracking locking on my old G1 I mean fast...Man . Someone Please FIX this craziness...lol Help...
[Vibrant Android Development] aohmer:
Btw TMO re-tweeted this today.

@TMobile_USA: RT @SamsungMobileUS: We're testing software to optimize GPS on US Galaxy S. Expected updates avail. in Sept. Details & download to follow.

woo woo!

I thought I would add my two cents and give my report on my phone after doing both option 1 and 2. I had did option one after seeing it described on android central and I really didn't notice much of an improvement. But after reading this post and seeing option 2 and doing what it said my Vibrant now locks on almost immediately. Both indoors and outdoors. So by combining both options it has made a fix for my phone. Now I'm sure the official fix from Samsung will "correctly" fix the issue, but for me at least I don't know how it could get any better. I lock on in and out of the house in seconds now instead of minutes. To end a big thanks to all the tech guys that give us noobs the info.
[Vibrant Android Development] antonio91282:
i tried both methods. when i was done my gps locked on very quickly and accurately. however, after a few days i tried to use the navigation and it started to act up when it had to reroute my directions. it refused to find me after i went off the original route. later when starting the navigation app it thought i was exactly where i was when i went off my original route. however the maps was able to find me. sometimes when hitting my location in maps it freezes and force closes. i love this phone but thiis gps is really hurts.
[Vibrant Android Development] bradycl_84043:
Hmmmm.... and to add a little bit of flame to this fire, I installed GPS Test on my wife's G1 tonight. Not only does it lock onto 7 out of 7 birds from my *basement*, more importantly, where my Vibrant is reporting the time according to the GPS as 7 hours fast, the time on GPS Test on her G1 is exactly correct.
[Vibrant Android Development] Emama:
I used the first fix and now I can get 2-3 sat in use very fast.

But i have a question, so it fixed now, even i turned the use wireless network off.

so what is the point of using wireless network in the fix,? For even more faster lock?

I always turned off both wireless network and GPS when i don't use them for saving battery. So i just wondering if i need to turn on wireless network for location or i can keep disabling it.

I know that the GPS is huge battery consumer, but how about the "use wireless network for location"? If i never turn off 3g, so is there any differences turning on/off the wireless for location?
[Vibrant Android Development] designerfx:
wait a minute, is samsungmobileus the one that's unofficial or the official one?
[Vibrant Android Development] antonio91282:
if flash the zip file made by eugene 373 will i still get over the air updates? is the zip file a rom or will it leave my phone unchanged besides the gps fix?
[Vibrant Android Development] heygrl:
I wouldn't bother, the fix has a typo in it and won't fix anything.
[Vibrant Android Development] riot8ap:
Works for me, after a tweak

I too am having problems with my Vibrant, date on box is 07/06/2010.

Both methods in the OP didn't work, however, I used a slightly different twist that ultimately works. for now :D

Turn Operation Mode to MS Based. Instead of changing the server to supl.google.com, change the Server FQDN Type from custom to automatic. Android plugs in what appears to be my resolved IP address and after a reboot and turning on wireless the GPS worked.
[Vibrant Android Development] Emama:
omg..........

After doing the first fix, my gps start working in a minute....

And to see if I can get a faster lock...

I tried to do the second fix...

However, after deleting the GPS data,

It cannot get anything back in the Position Test..

nothing comes out even I put my phone outside for 20 minutes....

Edit: Oh I returned to the original setting, reboot and get GPS position again,

now can get 13 in view,

Edit 2: wow, after turning back to original setting and wait for the GPS position,

I can get 2-3 lock in few seconds only!!

Let me see if it can keep though.

[Vibrant Android Development] bradycl_84043:
Any devs that might know how to figure out how/why the local time is reported incorrectly by the GPS in the Vibrant as opposed to on the G1? I'm fairly convinced this is a major problem, if not *the* problem, preventing multiple satellites from locking...
[Vibrant Android Development] techspy:
I am interested in this as well. I noticed something strange with this yesterday. After being inside for a few hours (in a building that blocks almost all gps) I went outside and fired up gps test. It showed 12 sats in view, none locked, but showed the green GPS in use button and showed 20 or so feet accuracy. The time showed correct as well! After about 10 seconds it showed a lock on one sat and then the time changed to being wrong again. It seems the first lock is always one very low on the horizon and probably not meant to use at this location.

All this has got to be related.
[Vibrant Android Development] thantik:
Woah woah woah.....go outside? :o That's the thing with the big blue ceiling right? Won't I get mauled by a bird or something?
[Vibrant Android Development] Charlie Brown:
Hmm...

After going through all kinds of different settings "fixes" lol and what ever you would like to call it, I still revert back to stock settings. They work best for me, my wife, my brother in law and father in lawphone. Four phones purchased two weeks ago.

IMHO After two weeks of vigorous testing with any and all "fixes" one can think of. It's all the same if not worse! On two phones stock got me the most consistent GPS service.

stand alone,www.spirent-lcs.com accuracy 50

The truth is untill we get proper firmware/drivers for our GPS hardware (if its not a hardware issue) we are stuck no matter what we do. From all the posts and all the live comments I have heared, about 20% of them are positive for the Vibrant's GPS and the rest of us eighty percenters only lock on 1-2 maybe 3 gps sattelites at best! With gps lock coming in and out making our location jump over 20-50 meters.
[Vibrant Android Development] wangjt:
for what it's worth, I had to uninstall Rom manager then reinstall it from the market placecuz it kept crashing my phone. After it finished installing, I noticed my phone couldn't get a GPS lock at all. I was able to lock to an accuracy of around 15~20 feet before. Google Maps and Navigation was unstable and would FC on me frequently, even after a fresh reboot. I remembered about the fix permission in Rom Manager. I let it run, rebooted my phone one more time and now everything's fixed. My GPS still locks with the same accuracy. Not sure if my GPS being fixed is just a coincidence but worth a try for those who's GPS was working but all of a sudden stopped locking (and has root).
[Vibrant Android Development] marsupial99:
Yeah, it's bat country out there so make sure to bring your fly swatter when you go.

;)
[Vibrant Android Development] marsupial99:
I think that this post pretty much sums it all up nicely. I've tried various fixes and fiddling with gps settings as well and after a couple of weeks all that it really accomplish is that it made my phone completely unstable and unreliable when I tried to use GPS. It just started rebooting or freezing pretty much randomly even after I reverted back to stock settings. It froze few times even after I finally bit the bullet and reset the phone completely. I finally called T-Mobile and got a replacement Vibrant. I decided to leave the gps settings completely alone, except for enabling wireless network assistance in settings, and it is at least stable now. My gps location does occasionally go crazy but it always recovers location in a couple of minutes but I don't have any freezes or reboots at least which is a lot better than before. The time is definitely reported wrong as others mentioned because Copilot switches to night color mode automatically at about 4 or 5 p.m. it seems. I guess it takes its time from the gps system and not from the phone time. I really hope that Samsung can pull this fix out because if this continues indefinitely I will have to seriously think about replacing it somehow. Probably sell it though ebay and buy something else for full price since my upgrade through tmo is now so far away.
[Vibrant Android Development] andrioidNoob:
I did this

I am a noob (didnt even spell android right in my username) on these things and was a bit nervous trying this. Did it anyway and it worked great.

My issues with certain gps programs were with the gps the whole time. After this I am getting gps updates right away.

Easy to do and it works (at least for me). I suggest doing it.
[Vibrant Android Development] LSxChevelle:
Did the fix and worked great the first few times and now barely ever works...
[Vibrant Android Development] bagayas:
Same here. While in my home state HI, the GPS appears to work fine, tracking me fairly accurately while driving. However traveled to Guam and find that Maps puts me somewhere in NM.
[Vibrant Android Development] Fedburin:
I have the same problem...

Were you able to solve it?
[Vibrant Android Development] gthmcty1:
Okay I have tried them all and this has......

WORKED the best for me and is pretty damn accurate, I do not take the credit for this but I am passing it along and hopefully it will help you out as well

Server Config: Custom Config

SUPL Secure Socket: ON

SUPL Server: supl.google.com

SUPL Port: 7276

Operations Mode: MS Based

Accuracy: 100

Sky Hook: On

GPS lock on is relatively quick sometimes you have to hit the "locate" me button but it locks on and is pretty accurate, let me know if this works for you.

Made correction to Socket: OFF and put it back to ON....and it still works better than any other mod that I have tried ....THANKS Androidmonkey
[Vibrant Android Development] androidmonkey:
Secure socket off is not secure...
[Vibrant Android Development] M9x3mos:
I think the gps reciever used in this device is just a weaker reciever then what was in previous htc devices.

When trying to do optional fix by deleting gps data and was watching I never get accuracy better then 13m or higher. With mytouch slide using gps status I get accuracy around 5m or 8m.

Also where it lists gps sats found in finds 11 but only fixes * on one of them vs slide at the same time was getting 5 or 6.

So I believe is just a weaker reciever then others or there is a problem more with mine.
[Vibrant Android Development] heygrl:
Why would you make such a statement based on absolutely nothing at all? If the GPS isn't functioning properly comparing it to another phone would be stupid and pointless. The GPS receiver is newer than whatever they put in the midrange Slide and comes from the best in the business.
[Vibrant Android Development] SamsungGalaxySVibrant:
My gps is ruined, help!

Hello,

I own a vibrant with GPS problems. My stock settings use to get me 11 satellites in view, and usually 1 locked, if I was lucky I would get 4 locked satellites.

I've tried the "fix" here, and something happend to my GPS, it totally broke or something permanent has happend. After applying the fix, and various optional fixes, my phone now only views 1 satellite, before it saw in view 11.

I've reverted all settings back to stock, with no help. I've even done hard factory resets more than once, completely putting the phone back to factory default settings. Still my GPS seems to be permanently damaged, it still only sees 1 satellite in view.

Did I permanently mess up the GPS settings by trying these fixes? I have left my GPS test running for 3 hrs today while I was driving around, it jumped up once to 2 satellites in view, but that was the max I got.

Someone please, what has happend to my GPS? I use to see 11, now it only sees 1 satellite.

What happend to all the satellites it use to view, why is it only viewing 1 now! I've compared with a different non samsung phone, just incase all the satellites fell out of the sky or something, the other phone sees 12 and uses 9. What happend to my vibrant!
[Vibrant Android Development] SamsungGalaxySVibrant:
I don't think just b/c the reciever is a newer model in the vibrant, necessarily means its better than the slides. The slide has proved to be an excellent phone, with excellent GPS.
[Vibrant Android Development] radiopayola:
Of all the fixes that have been tossed around including settings changes, testing while outdoors, sprint epic files ported over to the vibrant, etc...; eugene's fix is the only thing that has worked for me. Lock times range between 10 and 30 seconds on average. I did have a 2 minute wait once out of about 15 tries.

Previously, getting a lock was impossible at times. Usually, it would take somewhere between 5 and 15 minutes....if ever. I highly recommend eugene's fix if you're rooted.
[Vibrant Android Development] SamsungGalaxySVibrant:
Can the moderators change the title of this thread

I'm wondering if the moderators can change the title of this thread. Obviously the title is false and misleading. None of the methods posted in this thread are a "fix."
[Vibrant Android Development] beproz:
GPS... FIXED

This was the perfect fix! Thanks to you.
[Vibrant Android Development] marsupial99:
You can also try what I did. Call TMO and get a replacement Vibrant. Once you get a replacement, don't mess with GPS at all (except for enabling "Use wireless networks" option) and wait for the official Samsung fix.
[Vibrant Android Development] cornfool:
sort of worked

Hi all, thanks for the wonderful forum. I have about a week to go in my 14-day remorse time :), still debating whether to keep the phone or not...

I did both the things mentioned in post 1 and lock is somewhat faster and gps accuracy is better. Now my location is usually 10 to 15 meters accurate and navigation using google maps seems to be decent. It is pretty useless when I walk around with it in my hand, my location jumps like crazy all around.

What do you all think, Would Samsung's fix be better than this ? if this is the best it can be I am inclined to just return the thing.
[Vibrant Android Development] Shrivel:
No one knows the answer to that question (except maybe Samsung, and they aren't telling).
[Vibrant Android Development] aohmer:
Well I hope that fix comes out soon, I have tried all the GPS "Fixes" along with the update ... and my GPS although now finds up to 12 birds .. it still only locks on 2 at the most .. so annoying.
[Vibrant Android Development] robavila721:
what IF this issue is dealing with hardware, do you all think we should bite the bullet and keep it, serves us right for taking a leap of faith, or should samsung/tmobile do a recall and replace our handsets with either an updated vibrant with working hardware or a phone of equal price?
[Vibrant Android Development] Coniglio:
I am in Germany! I went to NYC a few weeks ago and I've brought with me a Samsung Vibrant, Phone is great even thought something it get a bit "lagged" / "stuck", is it normal? Would it get fix with an update or something?

However, my main concern is that my GPS aint working correctly. I am living at my gf's place that is located in a small town, close to Aachen or Cologne. The thing is even before I've tried this fix my location on google maps was "right", it was showing where I supposed to be, with 90meters accuracy. This was with my WIFI ON. Without moving out of my position I turn off the WIFI and my position on the map totally changes. The accuracy range is about 1300 meters, and my location is wrong but is inside of this blue circle (the range). And it's always showing the same place.

I have tried turning on and off wireless network or different things, dunno what to do :(

Is it this gonna get fix soon?
[Vibrant Android Development] Coniglio:
I really dunno anything about mobile phones, so I am wondering how are you guys seeing when or how many satellites r u getting on the phone?

I have installed 2 apps GPS Status and another one that at the moment I am not able to remember its name. But I have no idea how to use them, one of them it doesnt even appears to work as I dont seen any movements :S.

I AM AFRAID that since I have bought this over craiglist while I was on vacations in NYC I wont be able to get my money back or any help from Samsung. :( :( :( :/
[Vibrant Android Development] Quiksilver78:
This is really odd. I can't type in *#*#1472365#*#*

Well, I can type it in, but nothing happens. The numbers just clear out. I'm running JP3 (Froyo 2.2) if that makes a difference.

I'm also on 'Factory Fresh' mode per se. Haven't installed anything other than the firmware itself.

Did the numbers change perhaps?
[Vibrant Android Development] Genesis1791:
So what are the odds of Samsung replacing our phones if its actually a hardware issue and they can't fix with a simple software update?
[Vibrant Android Development] bilboa1:
when ive no network access on a fresh phone no matter how long the phone looks for sattelites it will lock NONE at all.

I am therefore under the impression that it can ONLY get the gps data through the network at the moment. in theory the GPS gets the data from the GPS satellites (which takes 1min or so) and this data is valid for this area a month or something like that.

using the network to download this data speed up the lock. but not being able to get it from the satellites at all plain sucks!

(for whoever doesnt understand: this data is necessary to acquire the locks, its not the positioning data itself)
[Vibrant Android Development] ski309:
When I asked a T-Mobile representative through online chat, she said they would replace faulty phones if it turned out to be a problem with the hardware and not software. Take that however you want.
[Vibrant Android Development] belgadom:
editing /etc/hosts does help for me

All suggested fixes did not work for me. After deleting the secgps.conf file (I believe eugene373 suggested this), I noticed in the log files that the system was trying to access lbs.geo.t-mobile.com, a site that is not reachable in my operator's network.

So I created a fake dns entry in the /etc/hosts file:

66.35.236.25 lbs.geo.t-mobile.com

I stole this address from supl.nokia.com, be aware that nokia may change the ip address of their service in the future. you can use the address of any supl server that is reachable on port 7275

hope this helps people that are not on the t-mobile net with their vibrant

OF course you need to be rooted.

update: sept 1: it is probably a better idea to edit the customer.xml file and put the google or nokia supl server there. I will try this evening. This was a quick hack. I did not know which conf file is really used.

update 2: after one day, I must admit that the initial positive results seem tp have disappeeared, locking is slow again

[Vibrant Android Development] MV10:
I'm kind of surprised this thread is still a sticky.

I think I've read more posts about failures than successes.
[Vibrant Android Development] belgadom:
both lbs and ibs resolve at dns level, but I get no connection to the servers behind those names in the network where I am (europe)
[Vibrant Android Development] frankencat:
This thread needs to be

1. Unstickied

2. Re-named (remove FIX from title)
[Vibrant Android Development] deepsee100:
Following this thread and others avidly.

Agreed that the title should be changed if this is not a DEFINITE fix.

I'm very interested in this toy but if GPS standalone as well as A-GPS doesn't work its a dealbreaker and I'll follow my 'Desire'.
[Vibrant Android Development] Siks:
I'd wait just a little while yet before making a final decision as Samsung did promise an official fix for the problem this month.

Sent via my Samsung~Vibrant~

[Stock/Root/TayutamaExt4Lagfix]
[Vibrant Android Development] betoNL:
What you mean with "Standalone GPS"?

Offline GPS navigation works like a charm in my gs.

No need for A-gps and no need for internal gps receiver either.
[Vibrant Android Development] heygrl:
^ I think you're a bit late to the party. Samsung has updated GPS functionality and left all LbsTestMode settings the same so it would seem as if there isn't anything wrong here per say.. I do know that enabling MS-Based mode decreases initial lock time to seconds.

Some people are complaining about having a 10M fix. I don't know what they're expecting but 10M isn't horrible. I get down to about 20FT on the new leaked out firmware (JI2) and I'm happy with that. Standalone mode has long fix times though.
[Vibrant Android Development] techspy:
Also, the fix has fixed the incorrect time showing.
[Vibrant Android Development] Emama:
What u mean the update is a leak rom right?

One more thing, if i messed up the GPS setting, after update the fix will it turn all of them back to default good settings?
[Vibrant Android Development] teqhead134:
Hey guys, I recently tried the "fix", and had no change in pinpoint acuracy. Then just today I recieved the the OTA update. I then tried to revert back to the original settings, and can't get into the LBSTestMode. The numbers just disappear and nothing happens. Is there an alternative way to access the LBSTestMode menu, or is it fixed due to the update?
[Vibrant Android Development] ncr100:
After the Sept 22 Captivate update I can no longer access that GPS menu (*#*#1472365#*#*).
[Vibrant Android Development] drhonk:
Yupe, ATT blocked access to that menu. They also removed USB tethering feature.
